SHIPPING-CONTAINER AND BOARD FOR CONSTRUCTING THE SAME.

Specification of Letters Patent.

Application filed May 19, 19 15. Serial No. 29,212.

To all whom it may concern:

Be it known that I, STANTON W. Fons- MAN, a citizen of. the UnitedStates, residing at Pasadena, in the countyof Los Angeles and State ofCalifornia, have invented a new and useful Shipping-Container and Boardfor Constructing the following is a specification.

This invention relates to boxes and other containers designed forprotecting their contents from injury'during shipment and storage andfor holding together packages of goods, especially packages of cannedgoods for convenience of handling for shipment and for storage.

In the present state of the art, so far as I am advised, there have beenprovided for this purpose boxes of wood, and also boxes made of flatcorrugated and cellular pasteboard of various kinds, and it has beencustomary to construct said boxes made of pasteboard in a collapsibleform substantially such as I propose to employ in the most generalembodiment of this invention.

It is an object of this invention to provide a container of minimizedweight and maximized protective qualities, thesame being designed toresist to acomparatively maximum extent the stress and strain anddestructive forces to which a package of goods, heavy or light, islightly to be subjected of this invention, I will state that an-objectof this invention is to provide a container of minimum weight having astrength suflicient to sustain without liability of being determinedheight of stack.

crushed, a load of one thousand pounds distributed over an area of 9 by14: inches, the side dimensions of the container, so that containersconstructed in accordance with this invention having outside dimensionsof 9 by 14: by 5!; inches can be stacked in stacks such that the weightupon the top side of the lower one of said containers in a stack may beone thousand pounds, morelor less, distributed evenly over the top sideof'said bottom package without any danger of crushing the same; thusenabling the packages to be loaded into cars and stored in warehouseswith perfect safety for a. pre- Where the goods contained in thepackages are cans of fruit, vegetables, meat, fish and the like, theweight of each package is the Same, of which.

being handled, stored or transported. As an illustration of thepractical resultoonsiderable and it is an object to insure safety of thesame, whether said cans be of glass or of sheet metal.

An. object of the invention is to accomplish all of these advantageousresults-at a minimum expense and with the usual apparatus and materialsat the command of the ordinary box manufacturer.

,All of these objects I have succeeded in accomplishing by thisinvention after a period of about three years of careful application andexperiment toward the solution of the problem. I

The invention may be understood by reference to the accompanyingdrawings.

Figure 1 is a perspective View of a container constructed. as acollapsible box in accordance with this invention and erected ready toreceive the goods. Parts are broken away to expose the structure. Fig. 2is an enlarged piece of board from which boxes corresponding to the boxshown in Fig. 1 may be constructed, parts being separated to illustratethe construction. Fig. 3 is an enlarged sectional detail of a corner of.a box constructed in accordance with the invention. Fig. 4: is anenlarged section of the board of which boxes corresponding to PatentedNov. 23, i915.

said box shown in Fig. 1 may be constructbers, 1, 2, 3, 4, and endmembers 5, 6, forming continuations thereof to fold over and close theends of the container. The wall is cellular, being constructed of aninter mediate bent sheet 7 an inner. facing sheet 8, and an outerindurated plural ply sheet 9, said sheets being unitedto. form acellular structure, substantially" shown in Figs. 3 and 4:; the innermembers of thestructure being crushed or creased as at 10 to allow thecontainer to be constructed and erected or collapsed as occasionrequires.

I The inner facing 8 "and the intermediate Sheet 7 may be of P per orthe like, as

shown in Fig. 3 or the inner' facing may be lplural ply as shown at 8 inFig. 4, and may 105 In the drawing, Ihave shown a container having acellular wall formed of .four memgreater strength and rigidity than iscalled The intermediate sheet is shown corrugated, but it is understoodthat any cellulat'ed structure or form may be employed, and that saidsheet may be honeycombed, indented or otherwise formed with undulations,wrinkles, or irregularities, impressions, or cavities of such acharacter that when "the three sheets are united, as shown in Fig. 3,the board thus formed will be of cellular structure.

The sheets 7 and 8 may be-of a soft and yielding character, and the. aircontained in the cellular body is confined by the folds formedby bendingthe board transversely of the corrugations. Suchfolding closes the cellsand confines the air in a well known manner so that the plural plyindurated outer facing 9 in combination with the closed air cells,constitutes a sheet of'unexpected strength and rigidity which isincreasedin the structure shownin Fig. 4.

. The intermediate body 7 may be united to the facings 9 and 801's byany suitable medium, either silicate, paste, glue or other cementingmaterial.

The board may be constructed by cementing one side of an ordinarycellular pasteboard formed of soft paper arranged with two flat sidesand an intermediate corrugated or other cell forming sheet of paper,-

the indurated facing being applied to one side of said board in one ormore plies, united thereto by silicate, or other strong cementingmaterial.

By this invention I have provided a board having an indurated facingstrengthened by a cellular structure united to one side thereof, saidcellular structure having a plain surface opposite the indurated facing,as clearly shown in Fig. 3.

I am aware that corrugated board has been manufactured and been in usefor the making of shipping containers, I am also aware that two or moreply pasted fiber board has been manufactured an used in the making ofwhat is known as solid fiber shipping containers.

It is a novel and new invention to use a solid fiber board, (and what Imean as solid fiber board, is two or more ply paper pasted board, theadvantages gained in constructing a corrugated board box using two ormore ply pasted board for the faces, he in i the fact that the pastedboard is more rigid,

together,) in connection with corrugated tougher and less liable to betorn or punctured than a single ply pasted board and I have discoveredthat the combination of said two or more ply pasted fiber board with thecellular board set forth, affords a solution of a problem heretoforeunsolved, in

that it affords a container of maximized strength and puncture resistingqualities combined with minimized weight.

I claim:

1. A container having a cellular wall constructed of an inner facingsheet of yielding sheet material, an outer indurated facing sheet formedof two or more plies of paper pasted together and an intermediate bentsheet united to said inner and outer sheets.

2. The board set forth comprising facingsheets and an intermediatecorrugated sheet united together, one of the facing sheets being of twoor more plies pasted together.

3. The board set forth comprising facing sheets and an intermediatecorrugated sheet pasted together, one or both of the facing sheets beingof two or more plies pasted together.

4. The board set forth comprising facing sheets and an intermediatecorrugated sheet pasted together; one of said facing sheets beingmultiply.

In testimony whereof, I have hereunto set my hand at Los Angeles'California this 10th day of May, 1915.
